First off, "manipulative" is not an emotion. You could exchange "feels" with "seems" because language is important. It is not slightly ironic that programmer types can tend towards imprecise language when discussing EQ skills :-)
And sure, If by my words I am trying to avoid triggering your flight/flight/freeze response, I am technically "manipulating" you. In this context though, the manipulation is not obviously coming from a place of trying to get you to do something you don't intrinsically want to do (which is really the connotation you imply in your dismissal).
I had a coach teach me a valuable EQ skill that helps in these situations: You made up a story in your head that the speaker was trying to manipulate you into doing something that you didn't want to do. That's one story. Now come up with 5 more stories that could also be accurate. Sure, the 1st story could be the right assessment, but the other 5 have possibility as well. Why are you jumping on the 1st story as the only real one? By making that assumption, you have changed the energy of the whole exchange into a negative one unnecessarily.
Another perspective you could take when confronted with stilted language is that the person is trying (however ungracefully) to communicate with you in a way that shows they care about your emotional reaction. No matter the reason, it at least shows that they are taking your perspective into account, which is inherently better than not.
